Replicape is a high end add on board for BeagleBone Black featuring 5 TMC2100 stepper motor controllers, 3 heater MosFets, 4 fans and 6 endstops. It has support for 2 servos, inductive sensor and cold end monitoring.

8 bits community based, tested and supported electronics

Melzi is a low-cost all-in-one solution for Reprap and other CNC devices. It features an on board Sanguino clone using the ATMEGA644P or ATMEGA1284P. Its four axes are powered by Pololu pin compatible stepper drivers.

RAMPS has become the most popular, most used RepRap electronics from 2012 up until the present date (february 2015). It shares circuitry concepts (stepper driver, thermistor, heater MOSFETs, etc.) with many other electronics. Also note that the price of both the RAMPS board and the Arduino Mega 2560 as well as the Pololu drivers has been driven down by copycat manufacturers in China (warning: the quality of clone parts can vary a lot from manufacturer to manufacturer and even between lots from the same manufacturer).

Sanguinololu is a low-cost all-in-one Pololu Electronics solution for Reprap and other CNC devices. It features an onboard Sanguino clone using the ATMEGA644P though a ATMEGA1284 is easily dropped in. Its four axes are powered by Pololu pin compatible stepper drivers.

The SAV MkI is an affordable all-in-one Pololu Electronics solution for 3D printer devices. This 3D printer board electronics has been designed using all the great contributions and feedback from the RepRap CloneWars group Proyecto_Clone_Wars in Spain.

It improves upon the previous production-grade electronics set by adding well dimensioned logic-level power MOSFETS, SD card support, on-board regulated 3.3V to connect to 3.3V level peripherals such us Bluetooth, as well as improving on USB link's reliability and reducing cost by eliminating the FTDI UART chip.
The SAV MkI is a derivative of Teensylu and the Printrboard, an AT90USB1286 development board originally based on Sanguinololu. The Atmel AT90USB1286 MCU has an on-chip USB, removing the need for the FTDI UART (USB-to-serial) IC. On-chip USB means that you will get faster firmware upload times, communications, g-code transfer and reduce the time file transfers take from the host to the on-board microSD card. The AT90USB connects at any baud rate regardless of firmware configuration, and operates virtually free of serial communication errors/pauses.

Arduino Nano based modular RepRap electronics. Etchable. DIY
SinapTec uses the Arduino Nano. It shares circuitry concepts (stepper driver, thermistor, form factor.heater MOSFETs, etc.) with many other electronics that have the RAMPS form factor. The Arduino Nano is probably the cheapest Arduino board, with clones, that use standard RepRap firmware.

24/12 volts power input. At 24 volts power losses on cables are lower providing faster heating making it quicker to start printing;

All the firmware were developed with OpenSource development tools: ARM GCC, ARM GDB, OpenOCD JTAG Programmer/Debugger and Eclipse. We intend to continue developing firmware and expansion modules, for adding new features. We envision the R2C2 to became the "Arduino" of the RepRap world.

Open Source: R2C2 source files of PCB, schematic and firmware are available on R2C2 Github account and so every user can take advantage and improve/adapt/hack R2C2 for his own purposes.

Compatible Firmware

R2C2 firmware is a mix of the famous GRBL and TeaCup firmwares. Latest stable firmware binary file can be download here and is ready to flash using R2C2 USB bootloader.
